According to fan emails, it appears the Money in the Bank PPV will end up being a legit sellout as there are few seats remaining.

Possible Late PPV Match Addition
Following last night's segment with Big E and Rusev, it's likely a match between the two will be a late addition to the Money in the Bank PPV Sunday night, although it has yet to be announced by WWE.

With only four matches having been announced for the PPV, and the Daniel Bryan segment airing on the Kickoff show, there will likely be a couple more bouts added to the show on Smackdown, or late adds during the show on Sunday night.

They had an "ok" match at Payback, but ok isn't enough to keep me entertained... I hope it's better this time. The crowd's likely going to be dead for it, though.
